OBJECTIVES: Despite the importance of the protection of patients' health information in clinical settings, little is known about the awareness of this concept in nursing students due to the lack of a suitable measurement tool. Hence, this study attempted to redevelop the Patients' Health Information Protection Awareness Scale, and evaluate its construct validity and reliability for nursing students. METHODS: A cross-sectional descriptive study was conducted. Nursing students who were in their 3rd and 4th year were recruited from 10 universities in Korea to assess the construct validity, and 30 experts (27 nurses and 3 faculty members) participated in the content validation process. RESULTS: The content validity assessment indicated that 23 items were ideal. The assessment of construct validity using exploratory factor analysis revealed three factors: communication, management, and referrals. They together accounted for 54.1% of the variance in scale scores. The three-factor scale had good fit in the confirmatory factor analysis. Scale reliability was confirmed, with a Cronbach's alpha of 0.94 for all items. CONCLUSIONS: This study was the first attempt to redevelop the Patients' Health Information Protection Awareness Scale for student nurses. The 23-item scale was shown to be a reliable and valid tool. It facilitates the assessment of nursing students' awareness of patient information protection. Academic nursing programs and health organizations can use its scores to implement adequate education plans to safeguard information in nursing students.

BACKGROUND/AIMS: As a result of the rapid development of medical diagnostic tools, physicians require concrete evidence to evaluate the effectiveness of the tools. We aimed to investigate the effectiveness and additional diagnostic benefits of capsule endoscopy (CE) in patients with small bowel Crohn’s disease (CD). METHODS: We performed a systematic search of databases, including MEDLINE, EMBASE, and the Cochrane Library, as well as eight domestic databases. Two reviewers independently screened all references. Diagnostic data from the studies were collected, and a meta-analysis was performed. RESULTS: Twenty-four studies were included. In cases of suspected CD, CE demonstrated a superior diagnostic yield compared with small bowel follow-through (SBFT) and enteroclysis (EC); however, there was no difference compared with computed tomography enterography or magnetic resonance enterography. In cases with established CD, CE demonstrated a higher diagnostic yield only compared with EC. In the detection of terminal ileum lesions, CE exhibited a significantly increased detection rate compared with ileoscopy. CONCLUSIONS: The findings of our meta-analysis indicate that CE is superior to SBFT and EC in the evaluation of suspected CD cases. CE is also a more effective diagnostic modality in patients with established CD compared with EC.

The aims of this study were to determine the occurrence and variables associated with the initial intravenous immunoglobulin (IVIG) treatment failure in Kawasaki disease (KD) and to categorize differences in clinical characteristics between responders and nonresponders to initial IVIG treatment. Patients were classified into two groups. Group A included 33 patients who received a single dose of IVIG treatment and responded. Group B included 18 patients who received more than two doses of IVIG due to failure of the initial treatment. The mean duration of fever after initial treatment in group B was significantly longer than it was in group A. In group B, we found that higher bilirubin, aspartate aminotransferase (AST), polymorphonuclear cells (PMN) (%), and lower platelet values at baseline were independent predictors of persistent or recurrent fever in patients with KD. Coronary artery abnormalities were found in 8 patients (44.4%) in group B and in two patients (6.1%) in group A. We found that abnormal liver function tests and a lower platelet count at baseline were possible predictors of nonresponders to IVIG in patients with KD. There is a need for a prospective study focused on baseline hepatobiliary parameters.

Epoxy resin-based sealers are currently widely used, and several studies have considered AH Plus to be the gold-standard sealer. However, it still has limitations, including possible mutagenicity, cytotoxicity, inflammatory response, and hydrophobicity. Drawing upon the advantages of mineral trioxide aggregate, calcium silicate-based sealers were introduced with high levels of biocompatibility and hydrophilicity. Because of the hydrophilic environment in root canals, water resorption and solubility of root canal sealers are important factors contributing to their stability. Sealers displaying lower microleakage and stronger push-out bond strength are also needed to endure the dynamic tooth environment. Although the physical properties of calcium silicate-based sealers meet International Organization for Standardization recommendations, and they have consistently reported to be biocompatible, they have not overcome conventional resin-based sealers in actual practice. Therefore, further studies aiming to improve the physical properties of calcium silicate-based sealers are needed.

Purpose: This study aims to analyze the financial performance research trends in medical institutions and to suggest the necessity and future research direction for financial management from the perspective of nursing organizations. Methods: Financial performance research in medical institutions was extracted by combining the keywords ‘finance’, ‘nursing’, ‘medical’, and ‘hospital’ in three domestic and foreign online databases. 55 studies were finally extracted. Results: Of the 55 studies selected, 41.8% have been published after 2010, and 79.6% have been published in Korea. 83.6% of the studies used financial statements, and 74.5% used the financial ratio. Among the studies on the use of financial statements, 40 balance sheets and 41 profit and loss statements were used. Conclusion There were some limitations in deriving implications for financial performance management at the level of nursing organization. When establishing strategies for future financial performance improvement, it is recommended to prioritize nursing cost optimization and profitability enhancement at the nursing organization level.

Vegetative electrode infection after implantation of permanent pacemaker or defibrillator is an uncommon but a serious complication. Diagnosis of the lead infection is particularly important since surgical manipulation is usually required for its treatment. We present 3 cases of electrodes related infective endocarditis among the 154 patients who implanted pacemaker or defibrillator between 2001 and 2004 in Korea university hospital. These complications were difficult to diagnose because of ambiguous clinical manifestations and indeterminate transthoracic echocardiographic (TTE) findings and were finally confirmed by transesophageal echocardiography (TEE).

The eye irritation potential of drug candidates or pharmaceutical ingredients should be evaluated if there is a possibility of ocular exposure. Traditionally, the ocular irritation has been evaluated by the rabbit Draize test. However, rabbit eyes are more sensitive to irritants than human eyes, therefore substantial level of false positives are unavoidable. To resolve this species difference, several three-dimensional human corneal epithelial (HCE) models have been developed as alternative eye irritation test methods. Recently, we introduced a new HCE model, MCTT HCETM which is reconstructed with non-transformed human corneal cells from limbal tissues. Here, we examined if MCTT HCETM can be employed to evaluate eye irritation potential of solid substances. Through optimization of washing method and exposure time, treatment time was established as 10 min and washing procedure was set up as 4 times of washing with 10 mL of PBS and shaking in 30 mL of PBS in a beaker. With the established eye irritation test protocol, 11 solid substances (5 non-irritants, 6 irritants) were evaluated which demonstrated an excellent predictive capacity (100% accuracy, 100% specificity and 100% sensitivity). We also compared the performance of our test method with rabbit Draize test results and in vitro cytotoxicity test with 2D human corneal epithelial cell lines.

BACKGROUND: Bronchial anthracofibrosis (BAF), which is associated with exposure to biomass smoke in inefficiently ventilated indoor areas, can take the form of obstructive lung disease. Patients with BAF can mimic or present with an exacerbation of chronic obstructive pulmonary disease (COPD). The purpose of the current study was to investigate the prevalence of BAF in Korean patients with COPD exacerbation as well as to examine the clinical features of these patients in order to determine its clinical relevance. METHODS: A total of 206 patients with COPD exacerbation were divided into BAF and non-BAF groups, according to computed tomography findings. We compared both clinical and radiologic variables between the two groups. RESULTS: Patients with BAF (51 [25%]) were older, with a preponderance of nonsmoking women; moreover, they showed a more frequent association with exposure to wood smoke compared to those without BAF. However, no differences in the severity of illness and clinical course between the two groups were observed. Patients in the BAF group had less severe airflow obstruction, but more common and severe pulmonary hypertension signs than those in the non-BAF group. CONCLUSION: Compared with non-BAF COPD, BAF may be associated with milder airflow limitation and more frequent signs of pulmonary hypertension with a more severe grade in patients presenting with COPD exacerbation.

The Korean Society of Radiology and the National Evidence-based Healthcare Collaborating Agency developed guidelines for primary imaging tests and appropriate biopsy methods for thyroid nodules. These guidelines were developed using an adaptation process by collaboration between the development committee and the working group. The development committee, composed of research methodology experts, established the overall plan and provided support about methodological strategies. The working group, composed of radiologist experts in thyroid imaging, wrote the proposals. The guidelines recommend neck ultrasound (US) as a first-line imaging modality for the diagnosis of thyroid nodules in patients with suspected nodules, and US-guided fine-needle aspiration as a primary method for histologic examination of thyroid nodules.
